ISWPRINT(3) Linux Programmer's Manual ISWPRINT(3)NAME
iswprint - test for printing wide character
SYNOPSIS
#include <wctype.h>
int iswprint(wint_t wc);
DESCRIPTION
The iswprint() function is the wide-character equivalent of the isprint(3) function. It tests whether wc is a wide character belonging to
the wide-character class "print".
The wide-character class "print" is disjoint from the wide-character class "cntrl".
The wide-character class "print" contains the wide-character class "graph".
RETURN VALUE
The iswprint() function returns nonzero if wc is a wide character belonging to the wide-character class "print". Otherwise, it returns
zero.
ATTRIBUTES
For an explanation of the terms used in this section, see attributes(7).

What is the point of this? Whenever I close my shell it appends to the history file without adding this. I have never seen it overwrite my history file.
# When the shell exits, append to the history file instead of overwriting it
